Problem installing my latest update open wrt 19.07.1 (Archer D50 V1)

Problem installing my latest update open wrt 19.07.1 on Archer D50 V1

error code 4503

Have you tried flashing via TFTP (U-Boot + UART) as described in the installation instructions?

error in windows block #0

in linux timeout

Are you trying to flash 19.07.1 from factory; or sysupgrade an already installed OpenWrt version?

yes Im trying to flash 19.07.1 from factory

Then:

  • Why do you keep using the web GUI?
  • Did you follow the instructions linked in by @tmomas in Post No. 2?
  • Can you show us the serial output, in addition to the TFTP results?

Do you have a serial data connection?
